Okay an update after many months of abuse.... Ashcroft CV's are in and going very nicely, still have raptor front shafts going into the Ashcroft CV's. Thus far I have broken front crown wheel and pinion twice, transfer box 3rd diff and an unmentionable amount of rear shafts.... I have a pair of Ashcroft Crown Wheels and Pinions on order and will see what I manage to break after they are installed.

That’s what I would do. It’s the pipe with green “condom” over the quick release fittings.

Hey I’ve been super hectic busy at work the past few weeks so haven’t checked up on the post. Progress thus far, Raptor CV joint is pretty brittle. Had a tool maker friend look at them and he thinks material is too thin and over hardened making it very brittle. Submitted my claim to Terrafirma; they said joint won’t fail and asked me for pics and explanation of failure. 🤔 They approved a credit for the CV joints. And I ordered the Ashcroft CV’s yesterday. It will take 10working days to ship to South Africa and clear customs etc. im going to keep the Raptor shafts and use the Ashcroft CV’s as I didn’t have enough money for the Ashcroft shafts too. The Raptor shafts are also warranted for 5 years so when they fail I’ll order a set of Ashcroft shafts to replace them. Im going to try my hand at turning some REAR shafts in the Lathe and have the splines rolled on the end. I want something stronger than oem shafts but not unbreakable as I don’t fancy replacing crowheel and pinion every few weeks. Ill post updates on how the shaft building goes when I get there. Lol.

Yes I agree hard doesn’t always mean strong. Anyway I wanted to support a company any that’s represented by the company I work for, shows what being loyal does..... looks like the general consensus is that Raptor isn’t as good as they are made out to be. I think I’ll get the cv replaced and give it one more try but when it breaks again I’ll ask them for a credit and go for the Ashcroft as they have been proven to last.

Well according to their web site they are made from 4340 Chromoly. And equilevant to the Ashcroft in size and quality. Ball size and outer Bell is about the same as original. Without measuring it’s not obviously a different size. Heres a link to their UK supplier. http://www.raptor4x4.co.uk/raptor-4x4-hd-cv-joints-land-rover-defender-from-300tdi-discovery-300tdi-range-rover-classic.html

I was grounded on my g.box crossmember and was full lock reverse. But the front suspension was extended quite far so very little traction on the front wheel. I’m sure the original OEM cv’s I usually use wouldn’t have broken.

Just remember the Thor motor (or D2 V8) uses a rerun less fuel system and the early p38 used a return type fuel system. So make sure that the pump can run with out a return. Or install a pressure regulator off a d1 further down the line and use a return line. If you do that make sure it returns into the pump housing or you will have fuel starvation when the tank level drops below full. You can retain the td5 fuel filter too. Just need to blank the air bleed and return lines on the filter housing. What about stripping your d2 fuel pump out the housing and installing it into the td5 pump housing and refitting it. I’ve done that a few times in the past and it works well.

Hi guys, I generally don’t post on forums but find they are a great place to find information based on other peoples experiences. I bought a set of Raptor CV joints, and fitted to my competition vehicle. I opted for the Raptor joints as the company I work for is a Terrafirma distributor so I could get them a fair bit cheaper than the Ashcroft. This is the first time they sold the product so I’m kind of their test “customer”. Anyway the point of my post is I broke the one of the Raptor joints almost immediately in yesterday’s competition. Most annoying, considering that I had taken all my spare cv’s out the day before as the HD joints won’t fail.... All my mates are running Ashcroft and nobody has had an Ashcroft failure yet. I just want some input as I saw another post from 2016 mentioning the Raptor joints. So has anyone used the Raptor HD CV joints and had failures in the past? I’m hoping it’s just a faulty part and I won’t have repeat failures I have a D1 V8 with 33” tyres and lockers, the front locker was not on when the joint failed. I know the product is warranted for 5years but it’s senseless replacing HD cv joints 3times in a competition, I could just stick the standard stuff with the same results.
